SPECIFICATION forming part of Letters Patent No. 315,155, dated April '7, 1885.

Application' filed July '7, 1884. (No model.)

.To @ZZ whom it may concern:

Beit known that we, THOMAS MCCUDDEN, of St. Louis, Missouri,and ALFRED F. SHEAE LOCK, of Festus, Jefferson county, Missouri, have jointly made a new and useful Improvement in VheatScourers, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure lis vertical cross-section on the line l l of Fig. 3; Fig. 2, a vertical crosssection on the line 2 2 of Fig. 3; Fig. 3, a horizontal section on the line 3 3 of Fig. l; Fig. 4, a sectional detail on the line 4 4 of Fig. l, and Fig. 5 a sectional detail on the line 5 5 of Fig. 1.

The same letters of reference denote the same parts.

The present improvement relates tothe construction and combination of parts hereinafter described and claimed.

A, Figs. l, 2, 3, represents the improved device.

In place of delivering the Wheat to the scourer at the end thereof, as hitherto has been the practice, the wheat is delivered to the scourer at the side thereof, and to this end the wheat is delivered through the spout B, whose mouth b in width extends the length of the scourer, substantially as shown in Fig. 3.

The scourer G consists of the ends or heads c c, the brushes c c', and the beaters c2 ci. The

-heads c c are attached to the shaft ci, which from the shaft c3 and by means of' the bolts c be fastened at any desired point of adjustment with reference to the center of the scourer.

The beaters c2 are, by means of the bolts ci, fastened to the lugs cB upon the heads c, substantially as shown in Figs. 2, 3, 5. The scourer rotates within the concave E. The concave is composed of wire-cloth-such as wire-gauze-and it extends beneath the scourer throughout its length, and the wheat to be scoured is delivered between the scourer and the concave, as indicated by the arrows, Figs. l, 3, the wheat passed downward between the scourer and the concave, and is Iin`ally delivered into the spout or chamber F, Figs. l, 2, 3, and, by means of the customary suctionblast,(the means for generating which are not shown,) the particles loosened from the wheat are drawn upward through the spout or chamber F, as indicated by the arrows'in broken lines in Figs. l, 2, and the wheat is received below in the customary-manner. The effect of this mode of delivering the wheat to the scourer is, the wheat is scoured more thoroughly than in the ordinary way.

The beaters cz are useful in detaching such particles from the wheat as cannot well be detached by means of the brushes c.

Ve claim- The combination of the spout B, the casing D, the concave E, and the scourer O, c0nsisting of the heads c c, the shaft c, the radially-adjustable brushes c c', and the beaters ci c'", said spout being constructed to deliver the wheat along the entire length ofthe hori.- zontal scourer, substantially as described.
